The Aura of a Broken Dragon

"Charge!" Issei watched as they began charging. Instantly, he speared straight through a large group of them, cutting them down instantly. Feathers began falling, and Issei continued brawling. He appeared right behind one of the more powerful fallen angels, grabbing their wings, Issei watched as the fallen angel began fearing for the worst.

Issei ripped the wings off, dropping them down onto the ground... Looking into his eyes, the fallen angel could only see someone who has lost it all. Someone who wants to just end it all... Issei stared with an emotionless stare, watching as the fallen angel began screaming. Quickly, he snapped the neck of the fallen and they exploded into nothingness.

Another one bites the dust.

Issei watched as many of the fallen angels began forming a giant spear, working together to form one, while the others began appearing in front of the formation. Issei dashed straight toward them, there were hundreds of them. Some of them were six-winged, fallen angels, meaning they would require some work to kill. Using his aura, Issei expelled it, he didn't have much control over it, but he was going to abuse it to incinerate the flock of fallen angels in front of him.

The only ones left were the more powerful ones.

They looked at him in fear. Watching their fallen comrades melt in front of them, was a massacre.

"You monster.."

"Me... Monster... Why?" Issei said while killing off more of the fallen angels.

One of them was able to speak up about the fear that he was experiencing, said while backing away, "You're killing us all... With no remorse."

"You would have killed me. You didn't care, did you?" Issei appeared in front of the fallen who spoke, grabbing the fallen by the head and forcing him to look into his eyes. "I would have died and you all would have thought nothing of it. What's stopping me from doing the same?"

The fallen stayed silent.

"Answer my fucking question!" Issei screamed while gripping the head of the fallen. Still having his aura on, he began melting the fallen's face. "Nothing, when death approaches all, they begin begging."

Crushing the head, Issei had finally snapped. All that was left were the several fallen angels that had begun forming the large light spear.

"Let's see how you deal with this, demon!" They screamed before throwing the spear straight at Issei. Embracing for impact, Issei knew that he wouldn't have been able to move fast enough, especially when multiple of them were putting all of their force into the spear...

Watching it in slow motion, Issei continued observing as the spear made contact with his body. His aura was able to withstand the piercing effect, taking most of the brunt of the damage before Issei felt the spear explode right in front of him. Sending him flying back into the ground, blood beginning to leak through his body, the color of the dirt beneath him turning crimson. Everything was falling apart.

Hundreds to nearly a thousand fallen angels were massacred by Issei leaving only a few to deliver the final blow. His physical body couldn't handle the pain anymore and gave out. On the ground, watching as the fallen angels began lowering themselves, descending down to him. He watched as they prepared a light spear...

"Finally, you human, you were a monster to us, but with your death. We maybe could finally get promoted by Azazel." They began laughing, as they formed a light spear. "The others? Well, we can think of them as collateral damage."

Looking at the fallen angel's face.

Issei won't accept this at all. He tried moving, but his body was too damaged. He wasn't going to die here...

He could only remember his parents. If he died, what would happen to them? They did so much for him. They were the only people that truly cared for him in this cruel world. He needed to make sure that they were safe. He needed to keep his promise of returning home safely. Seeing his mother's smile, seeing his father every day, He needed to move! He needed to get up. Why couldn't his body listen to his mind? Get the fuck up!

"Now, let's end this!" No! No! No! He couldn't allow this. Clenching his fists, Issei tried to slam his hand down to move, but his body was moving too slowly. Where is Ddraig? Where is his partner?

His emotions were going haywire, losing control with his anger and desperation taking over his mind, Issei began expanding his aura. He was losing control. "Never will I be hurt again! NEVER!"

Issei repeated once more, shaking his hands and slowly getting up. This was nothing, Issei had walked through pain worse than this. He had a hole in his chest, and he was able to move around somewhat before the blood loss got to him. Why couldn't he move here?

"Well, it was a good run, kid. Humans, they always are a nuisance." The fallen angel said appearing right above him.

The world was going to hurt him. The world was going to hurt his family if he didn't get up. Tears of pain, desperation, and anger began flowing down his face. "Would you look at that? He's going to cry." They began laughing.

Issei began laughing as well. That laugh... It was so similar to hers.

"Would you die for me?" He remembered her laughing at his desperation.

'I should have aimed to kill her... I should have come around and made her feel what I felt. Issei began screaming in his head.

His anger for Raynare reached a whole new level. What if she's the one behind this? What if she was watching? No, he will never allow her to win against him again. Never will he allow her to hurt him again. He clenched his teeth to the point where blood began pouring out his teeth.

He snapped...

"It's my turn to think for myself," Issei whispered while blowing up with his aura. "This world is against me. So be it. I will win against the world alone."

His aura began expanding.

[Boost]

That sound blasted throughout the area. Dread began being apparent on the fallen angels' faces as they watched Issei slowly getting up.

The Boosted Gear, like any other sacred gear, senses the user's emotions and reacts to them accordingly. Issei's emotions were so out of touch, out of control that they forcefully awakened the Boosted Gear and awakened another being.

"Partner, I apologize for leaving you alone to fend off the world. You fought with everything you had, even against an entire legion. Now, it's the both of us fighting. We will show blood to them all."

Issei could only hear bits of his partner and smiled...

"Let the process begin."

With those words, Issei began feeling an overwhelming flow of power circulating throughout his body. It was the Boosted Gear in all its glory back to its peak performance.

That was when the Boosted Gear began mutating. Expanding throughout his body, Issei began changing. Black plates of armor began engulfing his body, and the red-crimson aura of the Boosted Gear began overwhelming his blue aura sealing it within the armor. His eyes began giving off the murderous intent that he always had during the battle.

In an instant, a huge explosion took place, evaporating all life that was in proximity, including the fallen angels. Nothing was left besides a desert filled with lava lakes... Issei was in the middle of the deserted land with his eyes glowing red.

"Balance Breaker"

That was all that could be heard. He had achieved the forbidden skill. He had mutated such skill. He had become a monster built to kill all those who will wrong him. His power skyrocketed with the evolution that he just achieved. Reaching into the realms of the juggernauts of the supernatural world.

He walked along the path of bloodshed. He was once a joyful idiot that wanted nothing more than a woman to be beside him. It all turned upside down the moment that he did get one. That huge part of his life, a dream, had turned into an eternal fear that he will never recover from. He didn't need anyone besides his parents and partner, he didn't need any teachers besides his partner, and he didn't need to be used ever again.

A couple of hours after the massacre, Issei was able to leave the area safely. However, someone else had entered the behalf of someone else's order.

"Albion, what the hell happened here?" White dragon armor could be seen in the air floating in its supremacy, elegance could only describe the being.

"A massacre... Azazel had said that a large legion of fallen angels had been sent toward this area for some research purposes. Thousands of them were within this area and..." Albion paused to allow his partner to think of what happened.

"Not a single one survived. They all are dead."

"Vali, whoever did this, they must have done the same to Tiamat." Albion and his partner, while moving towards this area, had found Tiamat's body on the ground dead with the flesh beginning to decay.

"We need to tell Azazel. There seems to be a serial killer walking around the supernatural world."

"For them to kill all these high-class fallen angels, this being is a threat. A true threat, Albion was impressed with the massacre. It reminded him of what would usually happen during the Great War. It reminded him of when the world was ready to fight when the world was ready to shed some blood for what's right, it reminded him of the great times, the peak time for him.

"Do you think it was the Red Dragon?"

"Highly unlikely, Ddraig wouldn't have been this aggressive, especially with the years going by. He would have definitely stopped his host from doing this massacre in fear of going to war with an entire faction." Albion said calmly while his partner continued staring to see the destruction. Never had he ever seen a land be destroyed to this point nor had he seen someone incinerate an entire legion of fallen angels.

"We need to leave. Azazel will be waiting for us." The white dragon emperor said before soaring through the sky to get back to Azazel.

Albion and his host were shocked in seeing such a scene. The world had been too afraid of causing violence with each other in fear of going to war. Another Great War would bring destruction to all factions.
